The Reason Why Moms with Strollers Flock to the Sunshine 60 Observatory on Weekday Afternoons

1. What is Happening Now: The Phenomenon of "Mom's Park" on Weekday Afternoons

In the summer of 2025, at the newly renovated Sunshine 60 Observatory, moms pushing strollers are a common sight during weekday afternoons. Media reports indicate that about 30% of visitors are moms with children, and 15-20% are tourists. Factors such as "free leisure sheet rentals," "crawling spaces and picture books," "well-equipped baby rooms," "indoor safety," and "affordable prices" are analyzed as contributing to the attraction.Maido News

The core of this "phenomenon" lies in redefining the observatory from a **"place to view" to a "park where you can stay longer."** The following sections will delve into the reasons why moms gather on weekday afternoons, from the perspectives of facilities, pricing, rules, flow, and surrounding activities.

3. Seven Reasons Why Moms "Flock" on Weekday Afternoons

3-1. Time-Limited Picnic with Bring-Your-Own Lunch (Weekdays 11:00-14:00)

• Weekdays only, food and drinks can be brought in and consumed in designated areas (except during busy periods like Golden Week and Obon). You can spread a sheet on the indoor artificial grass for a **"sky picnic"** unaffected by the weather.Ikebukuro Sunshine CityIkebukuro Sunshine City

• The official FAQ displays the rules for bringing items (prohibited items, area map).Bringing items outside of designated times is not allowed, and taking your trash home is the principle.Ikebukuro Sunshine City

Point: The time setting aligns with the daily rhythm of infants (morning activity → lunch → afternoon nap). It's easy to warm baby food and share meals, balancing **"children have their usual taste" × "adults on a low budget."**

3-2. Baby-Friendly Infrastructure Fully Equipped Inside

• The **baby room (nursing room)** is equipped with diaper changing tables, private nursing rooms, hot water dispensers for formula, microwaves, baby chairs, and dining spaces, and men can also use the baby room itself (private nursing rooms for women only).Ikebukuro Sunshine CityIkebukuro Sunshine City

• The crawling space is exclusively for infants, with safety cushions. Picture books are also available.Ikebukuro Sunshine City

Point: Warming baby food, nursing, and diaper changes can be completed on one floor. It lowers the hurdles of the burdensome "outing with a baby."

3-3. Stroller Admission Allowed / Temporary Storage Available Inside

• Strollers are allowed inside. Temporary stroller parking is available inside.Ikebukuro Sunshine City

• Rental strollers are available not at the observatory but at the main Sunshine City (limited number).Ikebukuro Sunshine CityIkebukuro Sunshine City

Point: With options to "park upstairs" and "borrow downstairs," it's easy to plan routes even when operating solo.

Point: "One adult + preschooler" is effectively 700 yen on weekdays. It's easy to step into for mom gatherings and infants' **"first high-rise experience."**

3-5. All-Weather, Air-Conditioned = Safe Even in Extreme Heat or Heavy Rain

• In the indoor integrated park space, extreme heat, strong winds, and rain are irrelevant. Seasonal decorations and themed events are also held.Maido News

Point: Avoiding the risk of heatstroke while **"moving the body."** Functions as a **"refuge"** during extreme summer, winter, and pollen seasons.

3-6. Safety Design and Staff Patrols

• The management standards of a paid facility (cleaning, vigilance) and child-oriented designs with cushions and step considerations are found throughout.Maido News

Point: "Safety = Mom's Free Time". The environment where moms can talk while children play is rare.
